My lens baby tilt-transformer is broken :( :(

My lens baby tilt-transformer is having issues with keeping the lens locked on... I need help! Any advise I'm happy to have.

The issue:
The small pin that normally holds slots into the lens (Nikon) from the tilt-transformer adapter is no longer pushing in and staying in upon mounting the lens. This allows the lens to freely twist left (changing aperture on G-lenses) and right unlocking itself from the adapter, which is my biggest concern.

There used to be a tension (or spring of sorts) that used to hold the pin out, locking the lens (Nikon) into the adapter upon mounting.
